Cellulose-Based Polymers for Packaging Applications

Cellulose-Based Polymers for Packaging Applications 483 Table 21.1 Chemical composition of some common natural vegetable fibers. 

While PVOH and the vinyl acetate (co)polymers would not typically be considered to be compatible, the grafting achieved during polymerization and the resultant morphology yields useful and compatible compositions. The presence of PVOH yields good adhesion to cellulosic based substrates for wood glue, non-woven binder, and paper based packaging applications. The miscibility of PVOH with cellulose has been demonstrated, providing a rationale for the excellent adhesion [30]. 

Later, Kumar et al. (2011) used mathematical modeling technique to determine properties of bio-nanocomposites based on starch, proteins, and cellulosic polymers. They also discussed experimental techniques to determine the mechanical, barrier, thermal, and rheological properties of bio-nanocomposites, which are significant in assessing the performance for the application as food packaging materials.
